CURVED COMBINATION CONVEYORS

Capacities up to 120 tph (Wheat @ 750 kg/m3).

  • Curved machines used to feed elevator boots remove the need for elevator pits.
  • Replace a belt and bucket elevator and horizontal conveyor with one curved 90° from horizontal to vertical (Capacity up to 50tph).
  • Benefit of reduced number of machines and hence easier and quicker installation and less wiring work.
  • Horizontal / curved machines can be used to enter buildings and follow the roof line for maximum height.
  • Combination machines are made up using our market leading horizontal conveyor and flight elevator designs.
  • Angled Combinations allow machines to be fitted into existing plants and buildings more easily.
  • Mechanical reception pits can be fitted to all horizontal / inclined combinations.

INDUSTRIAL DEEP FLIGHT CURVED CONVEYOR

Capacities available from 60Tph to 350Tph.

  • Angles up to 60° (in 10° or 15° increments)
  • 4 heights & widths available.
  • All bolted & riveted heavy duty construction.
  • Forged steel chain with HD commercial spec plastic flights (suitable for all cereals & pulses as standard in agricultural and commercial applications).
  • Ideal for feeding in to an elevator bucket when avoiding pits in the concrete.
  • Inlet options include mechanical receptions & trench intake hoppers.

MECHANICAL RECEPTION HOPPERS & TRENCH INTAKES

RECEPTION HOPPER

  • Manufactured in lengths from 3m to 6m and double this when units are used in tandem.
  • Hoppers enable trailers to be tipped into a mechanical pit above ground. This is especially useful when there is a high water table and deep pits are not possible.
  • Alternatively hoppers can be situated below ground to allow drive over access.
  • The ground works only require a simple rectangular pit.
  • Mobile machines are also available.
  • Hoppers can be fitted to almost any of our chain and flight conveyors or our chain and flight conveyor / elevator combinations giving complete flexibility.
  • Galvanised construction is standard for all capacities up to 600 tph.
  • Inverter control is not required as there are 2 separate control slides with operating handles for flow control.

TRENCH INTAKE

  • A more cost effective alternative to a reception hopper.
  • Lengths from 1.5m upwards.
  • Narrow and compact, perfect for existing trenches.
  • No intake hopper.
  • Capacities up to 120 tph.
  • Requires an inverter to control the flow rate.

BELT CONVEYORS

Trough form range of belt conveyors are suitable for light duties and agricultural applications. Widths range from 300mm to 1000mm wide. Ideal to fill large stores, the belt conveyor can be positioned in the apex of the roof. A tripper can then be winched along the length of the belt conveyor to discharge product all away along the floor store. It is suitable for a variety of chopped, straw, pellets and grain.

The Tripper unloading device can either be motorised or hand operated. The hand operated version is simply pushed to the desired location and secured using the simple locking device. The motorised version is cable driven using Perry long proven capstan style winch drive and may be moved in either direction , with the belt either moving or stationary, loaded or empty.

Two manually adjusted tensioning screws are fitted to the Tail End. The tensioning screws can be readily disengaged to quickly generate slack in the belt for making joints , cleaning or other maintenance tasks. The belt is of a PVG compound type , with a Polyester carcass , giving excellent oil , mildew and rot resistance, flame retardance to ISO 340 and a satin top cover finish for improved product  release. Other belt types can be grip face or Chevron for use on inclined applications.

U THROUGH SCREW CONVEYORS AND AUGERS

Standard diameters are from 100mm to 600mm. Larger diameters and machines for specialist applications can also be manufactured on request.

CONSTRUCTION OPTIONS:

  • All flighting, screw conveyors and augers can be manufactured from mild steel and painted or hot dip galvanised or from Stainless steel.

DRIVE OPTIONS:

  • Vee belt drive from the motor directly to the shaft.
  • Gearmotor with final chain drive to the shaft.
  • 90 degree gearmotor drive directly coupled to the shaft.

FLIGHT TYPES:

  • Rolled flighting from 5 or 6mm mild steel in full pitch or 50% or 60% pitch for standard applications.
  • Segmented flights in various thicknesses of mild steel or from hardened steel to suit more arduous applications.
  • Variable pitch flighting for bin dischargers.
  • Ribbon flight for handling sticky materials.
  • Paddle flights for mixing applications.

A manually adjusted fixed brush is fitted, which will give excellent belt cleaning under most conditions. For more demanding conditions Rosta suspension units can be added  giving a spring loaded brush or scraper as required. In exceptional situations, rotary brushes or proprietary scrapers may be fitted. In all cases adjustment and servicing of the cleaning device is straightforward. Provision is also made for fitting cleaning devices for the underside of the belt if this is found to be necessary.
